LTR Standard Deck Wet Aluminum Block

from $6,625.00

2,000+ HP LTR Gen V LT Race Block

The new foundation for four-digit power.
If you’ve reached the limit of the factory LT block, or you simply want some extra piece of mind on your next build, then this just may be your answer. The LTR-SD10X is a U.S.-made, all-aluminum Gen V LT race block engineered for extreme boost, big cubic-inch builds, and the kind of durability the OEM casting simply can’t deliver. Designed to accept OEM LT accessories but built with aftermarket-level strength, this is the block serious LT builders have been waiting for.

Whether you’re chasing 1,000+ HP street reliability or 2,000+ HP competition abuse, the LTR gives you the confidence to lean on it — lap after lap, pull after pull.

Key Features

Cross-braced lifter valley
Adds rigidity and individual oil drain-backs for high-rpm stability.
0.750" deck / 0.625" skirt walls
Massive structural strength where LT blocks normally fail.
Fully reinforced casting + HIP process
Hot Isostatic Pressing removes porosity and maximizes material density.
Billet steel main caps w/ domed design
M10 studs + side bolts + dowels = maximum crank stability under boost.
120 lb total weight
True race strength without the iron-block penalty.
Priority main oiling
Oil is fed to crank and rods first — critical for high-rpm, high-load setups.
Ductile-iron sleeves
Thick, shock-resistant, and ready for big bore + big cylinder pressure.

Rear cover + gasket + hardware
Plug kit & oil galley barbell plug
